On this note, but slightly tangential, there are a bunch of third party
gnuradio plugins that are not being kept up to date and even no longer work
with gnuradio without significant changes. (E.g., top block vs flow graph).
Do you think we can create space in SVN somewhere for the updated versions
of these codes? I'm thinking about gr-ucla and maybe the BBN 802.11 stuff as
well.

There are two issues with this.
The first is that the software you describe seems to not have a
maintainers, and thus the bit-rot has set in. Having it in our SVN
doesn't change anything.
Secondly, with a few very rare exceptions, the host software in our
repository has all of its source code copyrights assigned to the Free
Software Foundation. So, even if we had committed maintainers for
this 3rd party code, we'd need to get copyright assignments from the
original authors.
That said, I'd be happy to help you and/or others to get them up to
date. Since they are all GPL, there is no issue with hosting them
somewhere else and patching them up to be current. We could even have
a wiki page dedicated to these efforts.

I'd like to bring this back up. I think Dan is poking at something that
has really bugged me for some time too. I think there is a ton of GNU
Radio code floating out there that is potentially extremely useful to
other people, that is never adopted in to GNU Radio because the barrier
of entry of code into GNU Radio is extremely high.

Copyright assignments, developer branch, QA code, following conventions,
awaiting approval, hesitation of maintainers to let in code they're not
familiar with... let's face it, getting code in to GNU Radio if it's not
a bug fix is a serious hassle that not everybody has time for. I
completely understand the reason for all of the above, but it's the
reason why we need something for 3rd party software.

There have been tons of postings to the list about projects people have
done, that maybe only work with a certain snapshot of GNU Radio. I
think this is OK. For example, someone might want to work with the
gr-ucla code and they don't care about new enhancements to GNU Radio
which make it unworkable. They check out a snapshot, and gr-ucla code.

So, you're probably thinking: OK so why do we need 3rd party support,
they can just check out the gr-ucla code and then an old version of GR
and be happy. Well... if they went to update that gr-ucla code they
need to contact the UCLA people. Whereas if there was a third party
repo, they could just makes changes for example, upgrading it to work
with the current GR release.

Additionally, 3rd party support is a great way to gather code for
someone to look at what else is available out there. For example, there
was multi-path code someone posted a while back that they had to go
through some hassle to setup their own server to host it. That server
is likely down by now. If there was some additional repo they could
commit it to, we'd have it right here right now to work from, and so
could other people.

Also, I spoke with Kyle that he revamped some of the OFDM code and has
been trying to get it in to GR but has had problems with either contact
or acceptance of his changes. I'm sure the code could definitely be
used by others... I think there should be somewhere that Kyle could
upload his code and let others use it.

Maybe an additional SVN is what we need. Maybe a GIT repo. A wiki so
that people can provide some information about their code. We need
something. I don't care of its officially supported by GNU Radio or
not, but I think it would certainly benefit the GNU Radio community.
